Struct ffmpeg::avcodec::AvFrame

source ·
pub struct AvFrame(*mut AVFrame);
Expand description

An owned AVFrame, i.e. one decoded frame from libavcodec that can be converted into a destination buffer.

Tuple Fields§

Implementations§

source§

impl AvFrame

source

pub fn new() -> Result<Self, AvFrameError>

Create a new AvFrame. The frame’s parameters and backing memory will be assigned when it is decoded into.

source

pub fn builder() -> Result<AvFrameBuilder, AvFrameError>

Create a new AvFrame builder that allows setting the frame’s parameters and backing memory through its methods.

source

pub fn dimensions(&self) -> Dimensions

Return the frame’s width and height.

source

pub fn format(&self) -> AvPixelFormat

Return the frame’s pixel format.

source

pub fn set_pict_type(&mut self, ty: c_uint)

Set the picture type (I-frame, P-frame etc.) on this frame.

source

pub fn set_pts(&mut self, ts: i64)

Set the presentation timestamp (PTS) of this frame.

source

pub fn is_writable(&self) -> bool

Query if this AvFrame is writable, i.e. it is refcounted and the refcounts are 1.

source

pub fn make_writable(&mut self) -> Result<(), AvFrameError>

If the frame is not writable already (see is_writable), make a copy of its buffer to make it writable.

Trait Implementations§
